Firstly, we propose the concept of key time nodes in radar\/jammer confrontation and analyze its predictability. Secondly, we analyze the radar-winning scenarios by considering the temporal constraints and construct the actual utility matrix of the radar. Then, we describe the optimization algorithm using radar-winning probability statistics based on the prediction of left game interval. Finally, we carry out a simulation experiment by comparing it with other anti-jamming strategies to verify the rationality, and the result shows that the proposed method can significantly improve the radar\u2019s winning probability in the confrontation. By using the proposed anti-jamming strategy optimization method just at the key time nodes, the imperceptibility from the jammer is improved, and its long-term superiority can be maintained in the confrontation.<\/jats:p>","DOI":"10.3390\/rs15153716","type":"journal-article","created":{"date-parts":[[2023,7,26]],"date-time":"2023-07-26T01:09:01Z","timestamp":1690333741000},"page":"3716","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Optimization Method for Radar Anti-Jamming Strategy via Key Time Nodes"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9219-0865","authenticated-orcid":false,"given":"Cheng","family":"Feng","sequence":"first","affiliation":[{"name":"School of Integrated Circuits and Electronics, Beijing Institute of Technology, Beijing 100081, China"}]},{"given":"Xiongjun","family":"Fu","sequence":"additional","affiliation":[{"name":"School of Integrated Circuits and Electronics, Beijing Institute of Technology, Beijing 100081, China"},{"name":"Tangshan Research Institute of BIT, Tangshan 063007, China"}]},{"given":"Jian","family":"Dong","sequence":"additional","affiliation":[{"name":"School of Integrated Circuits and Electronics, Beijing Institute of Technology, Beijing 100081, China"}]},{"given":"Zhichun","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Integrated Circuits and Electronics, Beijing Institute of Technology, Beijing 100081, China"}]},{"given":"Jiyang","family":"Yu","sequence":"additional","affiliation":[{"name":"Beijing Institute of Space Systems Engineering, Beijing 100094, China"}]},{"given":"Teng","family":"Pan","sequence":"additional","affiliation":[{"name":"Beijing Institute of Space Systems Engineering, Beijing 100094, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"633","DOI":"10.1109\/22.989948","article-title":"Electronic warfare systems","volume":"50","author":"Spezio","year":"2002","journal-title":"IEEE Trans.
